MILK STRAINER.

Application filed February 13, 1923. Serial No. 618,765.

To all wlw/m t 71mg/ concern.'

Be it known that I, ARTHUR O. S'iUBBs, a citizen of the United States, and a resident of Des Moines, in the county of Polk and State of lowa, have invented a certain new and useful Milk Strainer, of which the following is a specilication.

rhe object of my invention is to provide a milk strainer of novel construction wherewith milk can be properly strained and foreign material removed therefrom.

Still a further object is to provide such a strainer embodying a simple construction whereby milk may be passed through a wire thence through aY cloth screen or strainerl in such. manner as most effectively accomplishes the purpose to remove foreign material from the milk.

Viith these and other objects in view, my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects ccntemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 shows a vertical sectional view taken a little oit center through a strainer embodying my invention.

Figure 2 shows a horizontal, sectional view of the strainer taken on the line 2,2 of Figure 1.

Figure 3 shows a vertical, sectional view taken a little 0E center through the lower part of the strainer taken at right angles to the view shown in Figure 1; and

Figure 4 shows a detail, central, sectional view through the lower parts of the strainer.

ln the accompanying drawing, l have used the reference numeral 1() to indicate generally the milk receiving member which has a tapered bottom 11 open at its lower end and terminating in an annular downwardly projecting ange 12. The bottom 11 is designed. to lit in and above the flaring top of an ordinary milk can.

Mounted in the lower endof the bottom 11 of the milk receiving member is my strainer device proper.

Resting on the inside of the bottom 11 at the lower end thereof and arranged to iit said lower end as shown in Figure 1, is an annular flange 13 formed on the upper end of a downwardly projecting tubular member 14.

At its lower end the tubular member 14 has a short, inwardly projecting annular flange 15 terminating in a downwardly projecting iiange 16. Connected with and extending horizontally from one-half of the flange 13 half way across the top of the member 14, is a horizontal partition member 17 which at its inner edge has a vertical partition 1S extending downwardly and cxtending from side to side on the inside of the member 14.

The member 18 terminates at its lower end in a downwardly and laterally inclined flange 19. Secured to and extending upwardly from the other half of the flange 13, opposite the horizontal partition 17 a semi-cylindrical wall 2O above which is a top or cover 21.

A wire gauze screen 22 is secured to the edge of the top 21, wall 20, and the bottom 17, extending entirely across the opening at the open end of the half cylinder formeel by the member 20. Secured to the member 1S, approximately at the middle thereof, from end to end, is a downwardly extending bolt 23 which is screw threaded at 24, at its lower end.

v Secured to the flange 19 is a downwardly opening channel shaped member 30 extending across the lower part of the member 14.

It will be seen that the device just described which constitutes the upper half of the strainer proper is seated in the lower end of the bottom 11 and can be removed. therefrom by simply lifting such device. upwardly.

l provide a lower half of strainer comprising a cup shaped meinber'having a bottom 25 and the cylindrical side wall 26.

The side wall 26 is provided at its upper end with an outwardly extending flange 27 terminating in an upwardly extending flange 28.

Extending across the upper part of the bottom half of the strainer just described. just below the flange 27 is a cross bar 29, the upper surface of which is inclined from its center portion downwardly and laterally in both directions. Received on the flange is a gasket 31. y

A. sleeve 32 connects the bottom 25 at the center thereof, with the cross bar The cross bar 29 has a hole 33 therein, registering with the opening in the sleeve 32. The bottom 25 has an opening 3&1 therein which registers with the hole in the sleeve 32.

ln assembling my strainer, I place a piece of gauze 36 over the top of the lowerhalf of the strainer and then place the lower half 'of the strainer in position with the member 28 extended through the cloth, through the cross bar 29, the sleeve 32, andthe'bottom 252 A wing nut S is screwed on to the member.

for holdingthe two parts oi" the strainer' together.

In the use otl the strainer, the bottom 11 is seated in theila-ring upper;Y end ofthemillt can and' mi lk is then poured. into theimember 12 and will new into thebottomxgll andthen throu'ghthe wire gauze 22, whichwill strain' out'- any larger. particles of impurities, thence downwardly through the-'lett hand half. of. the gauze 36, thence across andundefrneath thec'ross bar-.29 and. thence? up wardlythro-ugh the other half otlthe'gauze-SG into the1com.-
